Mark,
I now realize you can't build just one :roll: . Maybe a 5e3 tweed deluxe, ODS and/or an 18-watt would be nice also. Or I could save money and buy a ready-made Alessandro, Cornford or Bruno - but where's the fun in that?

Interesting choice. How did you decide on that one? I didn't see any sound samples for it on the Eminence site.

On another topic:
When I was debugging the TW liverpool I had a problem with oscillation that sounded like a trumpet or trombone. It was affected only by the presence control and it went away when I disconnected the feedback signal. You probably guessed already that it was caused by positive feedback instead of the intended negative feedback. I fixed it by swapping the phase of the final output to the output transformer (and re-connecting the feedback signal of course).

After building many 1 x 12" cabs, all with different speakers, all Eminence.

Private Jack, Governor, Red White and Blues, Delta Pro.

Tried the Delta Pro after reading some speaker suggestions on the...huh... The Amp Garage... :roll: :oops: :roll: :shock: :lol:

Very nice build Dave, especially for your first!!! The cabinet came out clean, good job. This is my first post here, been "lurking" for a bit and just wanted to give you some props. I only recently came across this site and immediately decided i was gonna build something like an express after seeing builds like this, as soon as my current project is done that is...

Tubetwang,
Thanks for the Eminence info. Sounds like I should build a few speaker cabinets so I can try some of them.


Bruce,
Thank you kindly. I think you would enjoy building it.

Bruce,

Welcome to ampgarage and keep us posted on if you decide to build an express.

Dave,

Build that cabinet and give a shot of it when done. I always enjoy seeing what everyone is building, keeps me excited to build and create.

Thanks Mark, it's funny, I made a will call order last night and stopped at Mcmaster Carr this morning to pick up some more garolite, I changed my current build's layout a bit, I like KF's power supply board and filter cap set-up so my current build will now be similar to that. I have 100 turrets on the way and enough garolite left over to start "my express"... This hobby is addicting...

I asked Jim at Southbay Ampworks for his recommendation. I'll post his reply when I receive it.
Jim recommended the 65W M75 (small dust cap version). This is based on the information I gave him so your results may vary.
